Изобретение относитс к технике св зи и может быть использовано в телефонии.The invention relates to communication technology and can be used in telephony.
Известен способ контр.ол остаточного затухани канала св зи, заключающийс в передаче пр мого сигнала с одного конца канала св зи, приеме пр мого сигнала автоматическим устройством на другом конце канала св зи, передаче автоматическим устройством обратного сигнала и измерении уровн обратного сигнала.A known method for monitoring the residual attenuation of a communication channel involves transmitting a direct signal from one end of the communication channel, receiving a direct signal by an automatic device at the other end of the communication channel, transmitting an automatic signal feedback device and measuring the level of the reverse signal.
Цель изобретени - упрощение контрол путем передачи обратного сигнала одновременно с пр мым.The purpose of the invention is to simplify monitoring by transmitting the reverse signal simultaneously with the forward one.
Дл этого в описываемом способе обратный сигнал формируют непосредственно из пр мого сигнала, уровень передачи обратного сигнала измен ют в зависимости от пр мого сигнала и определ ют величину остаточного затухани дл каждого направлени передачи по значени м уровн обратного сигнала.To do this, in the described method, the reverse signal is formed directly from the forward signal, the transmission level of the reverse signal is changed depending on the forward signal, and the residual attenuation value is determined for each transmission direction by the values of the reverse signal level.
Дл осуществлени контрол остаточного затухани канала св зи с одного конца канала св зи передаетс сигнал определенной частоты и уровн ; Автоматическое устройство, расположенное гна-: другом конце канала св зи , принимает этот сигнал и ;передает-на. противоположный конец канала .св зи. сигнал другой частоты с. уровнем,, которой ..измен етс периодически от номинальной величины до величины, вл ющейс заданной функцией уровн принимаемого сигнала. Вследствие изменени уровн па конце канала св зи имеетс возможность измерить два значени уровн принимаемого сигнала: уровн номинальной величины принимаемого сигнала и уровн , изменивщего свое значение в результат (.: прохол дени сигнала по каналу св зиTo monitor the residual attenuation of the communication channel, a signal of a certain frequency and level is transmitted from one end of the communication channel; An automatic device located at the other end of the communication channel receives this signal and transmits-to. the opposite end of the channel. signal of another frequency c. level, which is changed periodically from a nominal value to a value that is a given function of the received signal level. Due to the change in the level by the end of the communication channel, it is possible to measure two values of the level of the received signal: the level of the nominal value of the received signal and the level that changes its value as a result (.: Of the signal through the communication channel

Способ контрол остаточного затухани капала св зи, заключаюпи1йс в передаче пр Moio спгиала с одного конца канала св зи, приеме пр мого сигнала автоматическим устройством на другом копце канала св зи, пе .)сдаче автоматическим устройством обратного сигнала и измерении уровн обратного сигнала , отличающийс тем, что, с целью упрощени контрол путем передачи обратного сигнала одновременно с пр мым, обратный формируют иепосредственно из пр мого сигнала, уровень передачи обратного сигпа .па измен ют в зависимости от пр мого сигиа .ла. 1. определ ют величину остаточного затухани дл каждого направлени передачи по значе1 11 м у)ови обратного сигнала.The method of controlling the residual attenuation of a drop of communication involves enclosing a Moio transmission from one end of a communication channel, receiving a direct signal by an automatic device on the other channel of a communication channel, and re. that, in order to simplify control by transmitting the reverse signal simultaneously with the forward one, the reverse one is formed and directly from the forward signal, the level of the reverse sippe transmission is changed depending on the forward sigi. 1. Determine the magnitude of the residual attenuation for each direction of transmission by the value of the 11 m s) of the return signal.
